Sympathetic nervous system stimulation causes what?
with stimulation of the sympathetic nervous system there will be a. constriction of the pupils b. dilation of the coronary arteries c. constriction of selected blood vessels d. profuse sweating
Heartbeat is governed by what body system?
Heart muscles has there own rhythm of contraction. The sinoatrial node has the fastest rate of contraction. That is why it governs the rhythm of the heart. You have the control of the autonomic nervous system over the heart rate. Stimulation of the sympathetic nervous system increase the heart rate. Stimulation of the parasympathetic nervous system decrease the heart rate.
Where do sympathetic postganglionic fibers end?
Sympathetic postganglionic fibers end in effector organs such as smooth muscles, cardiac muscles, and glands. They innervate these structures to modulate their activity in response to stress or stimulation of the sympathetic nervous system.
How might you feel when your sympathetic nervous system is simulated?
With current technology it is not yet possible to simulate a sympathetic nervous system
What is the abbreviation for the sympathetic nervous system?
The abbreviation for the Central Nervous System = CNS.
What system controls the flow of saliva?
The autonomic nervous system controls the flow of saliva. The production of saliva is regulated by both the parasympathetic and sympathetic nervous systems, with the parasympathetic system increasing saliva production and the sympathetic system decreasing it.
What is a Sympathomimetic?
Denoting a drug that mimics the effects of stimulation of organs and structures by the sympathetic nervous system.
What is the difference between sympathomimetic and sympatholytic drugs?
A sympathomimetic drug mimics the physiological effects caused by the stimulation of the sympathetic nervous system. Note the keyword : Mimic A sympatholytic drug oppses/ blocks the physiological effects caused by stimulation of the sympathetic nervous system HOPE THIS HELPS! :)
What causes sympathetic division stimulation?
with stimulation of the sympathetic nervous system there will be a. constriction of the pupils b. dilation of the coronary arteries c. constriction of selected blood vessels d. profuse sweating
What two mechanisms influence the force of cardiac contraction?
End diastolic volume and sympathetic nervous system stimulation
What component of the nervous system is associated with the fight or flight?
sympathetic nervous system.
How does the liver respond to sympathetic nervous system arousal?
Sympathetic stimulation of the liver increases glycogenolysis and lipolysis to make energy more available to metabolic processes.
What is the effect on blood pressure to an attack by a mugger?
Blood pressure would increase due to sympathetic nervous system stimulation.
Sympathetic nervous system stimulation causes what?
with stimulation of the sympathetic nervous system there will be a. constriction of the pupils b. dilation of the coronary arteries c. constriction of selected blood vessels d. profuse sweating
Sympathetic and parasympathetic nervous system's are subdivisions of what nervous system?
The sympathetic and parasympathetic nervous systems are subdivisions of the autonomic nervous system.
What nervous system gets your body ready for action in an emergency by increasing adrenalin and slowing down digestion.?
sympathetic division of the autonomic nervous system
What is sympathetic stimulation?
Sympathetic stimulations are signals to the body that imply stress. Sympathetic stimulation stimulates the sympathetic part of the peripheral nervous system and results in multiple response such as increased cardiac output, dilation of the pupil, inhibition of the smooth muscles of the gastrointestinal tract and urinary bladder, and erection of the penis.
